Mohr's circle is a graphical method used in mechanics of materials and solid mechanics to represent the state of stress (or strain) at a point in a material.
It allows for the visualization and calculation of stress (or strain) components on arbitrarily oriented planes passing through that point.
Key information obtained from Mohr's circle includes:
- Principal stresses (maximum and minimum normal stresses) and their orientations.
- Maximum shear stress and its orientation.
- Normal and shear stresses on any given plane.
It is a fundamental tool for stress and strain transformation and analysis, particularly for finding principal values.
It is not used for calculating bending moments, analyzing fluid flow, or measuring thermal expansion.
